You are supposed to build multi regional services if you need higher resilience.

Actual multi-region replication is hard and forces you to think about complicated things like the CAP theorem/etc. It's easier to pretend AWS magically solves that problem for you.

Which is actually totally fine for the vast majority of things, otherwise there would be actual commercial pressures to make sure systems are resilient to such outages.

You could also achieve this in practice by just not using us-east-1, though at the very least you should have another region going for DR.

Never said it was easy or desirable for most companies.

But there is only so much a cloud provider can guarantee within a region or whatever unit of isolation they offer.
